HP Spectre x360 convertible 15-df1211ng - Tablet mode not working

[Tapir97]

I recently bought a HP Spectre x360 15-df1211ng convertible.

My problem is that if I turn my notebook to use it as a tablet, the notebook is not automatically changing to tablet mode, even though its activated. 

I checked the registry key mentioned here, but that did not help. My device manager shows multiple unknown devices, but HP support assistant says all drivers are up to date.

These are Hardware IDs from the unknown devices:

Ven_8086&Dev_1903

Ven_8086&Dev_A379
Ven_8086&Dev_A324

Ven_10EC&Dev_525A
Ven_8086&Dev_A37C

I don't know if the unknown devices relate to the problem, but I find it odd that the device manager doesn't show me any sensors.

Please help.

For now, try these steps:

Please perform a hard reset on the notebook by following instructions from this link: https://hp.care/2nwQ054

Then perform these steps:

Please try these steps:

1. Go to the control panel

2. Go to Display

3. Go to Adjust Resolution

4. Be sure "Allow the screen to auto-rotate" is CHECKED.

Solution 1:

The keyboard in Windows 10 has an automatic detector to disable the keyboard and the trackpad as soon as it becomes a 'tablet'. To access it go to the following menu items:
Control panel (NOT SETTINGS) -> Keyboard (use icons) -> Keyboard Lock -> Auto-Lock the keyboard and touchpad (recommended)
You can use these settings to disable the keyboard in tablet mode

Solution 2

Some of the users who had a similar issue have mentioned in some forums that the issue is fixed by adjusting the angle of the tablet. When the laptop is rotated sideways it attempts to switch to tablet mode, even when you have not adjusted the screen angle. The sensing is done by an orientation sensor in the base of the laptop, not in the hinges. So, to turn the keyboard back on and to go to laptop mode try tilting the whole laptop towards you slightly and check.

Solution 3: 

• If it does not please perform a complete system recovery again to factory settings.
• Then install the latest version of HP support assistant.
• Please perform all Windows update again.
• Then update the Intel Integrated Sensor Solution Driver from https://hp.care/2syreDe and follow the on-screen instructions.
• Please run the Intel driver utility and update it from the Intel website.
• Also, ensure that you have the latest bios update by running HP support assistant.
• This should do the trick for you if there is no hardware issue with the computer.

Solution 4

Go to Device Manager > System devices > Intel Integrated Sensor Solution and ensure that the driver is enabled.
